IMPROVEMENT lNbAR-wHEl-zLs.

Specification forming part of Letters Patent No. 200,254, dated February12, 1878 application filed i June 15, 1877.

To all whom it may honorem:

Be it known that 1,'CHARLES E. GANDEE, of St. Louis, in the county ofSt. Louis and State of Missouri, have invented Improvements inOar-Wheels and manner of supporting same on axles, of which thefollowing is a specificaits cap removed to show the interiorconstruction.- Fig. 5 is a section of the plug for introducing thelubricant. Fig. 6 shows a section of the parts to form an airtight jointsurrounding the journal.

My car wheel or wheels do not form part and parcel of the car-axle-anadvantage, as will hereinafter appear.

A represents my car-wheel in its entirety, and as such it is cast orformed to have the following constructive features: A1, the carwheelproper, and A2 the sub-wheel. (See Figs. l and 2.) The car-wheel A1 has,further, the internal chamber B, (see Figs. 2, 3,) and likewise thesub-wheel A2 has an internal chamber, B. (See Figs. 2, 4.) Thesechambers B B communicate with each other by the annular passage b. (SeeFig. 2.) It is through the annular passage b that the journal of thecar-axle C passes to support the wheels.

I utilize the body of the car-wheel (its internal chamber) to answer thepurposes of the ordinary car-axle box. Hence the anti-friction wheels D(of which there can be the required number) are provided in the chamberB, and said wheels turn independently on their axis d, being so arrangedthat the periphery of the wheels shall engage the annular surface ofsaid chamber B, and also the periphery of the journal of the car-axle.(See Fig. 3.) Thus the car-wheel proper, so provided with wheels D,turns entirely upon rolling friction. In a similar manner I providewithin the chamber B' anti-friction wheels D', to turn independently ontheir axis d', and engaging the journal and annular face of theirchamber, (see Fig. 4,) and thus said sub-wheel is also supported onrolling friction.

The wheel A1 and its sub-wheel A2 are cast together, or formed to beunited. This construction is intended to counterpoise the carwheelproper. The sub-wheel resists any tendency on the part of the car-wheelto wabble, and keeps said wheel in a vertical or plumb line of action.

VE is the vcover or cap wherewith to close the open side of the chamberB. The cap is fitted to engage the bearing-edge at e, formed in thewheel A, and a packing, e1,is placed between the cap and itsbearing-edge, to form the needed air-tight joint. By means ofscrew-bolts the cap E is secured to the wheel A1.

The joint of the cap surroimding the axle is closed in the followingmanner: The cap E has, surrounding the axle, an annular projection, e2.This is screw-threaded. A sleeve, e3, is provided to screw on theprojection e2 of the cap, and at the point where said sleeve e3surrounds the axle the packings e4 and e5 are provided. (See Fig. 6.)The annular packing e4 (of rubber or suitable material) is made V-shaped internally, and in said V groove the `packing of hemp is held,and it is this latter packing which directly closes the joint around theaxle air-tight. The packing e4 is simply to retain and hold the hemppacking in place. .In like manner the cap E closes the chamber B', andin the joint of the sleeve surrounding the axle are also similarpackings. By this manner of closing the joints no air, dust, orimpurities can enter the lubricant-chamber.

The lubricant is introduced into the chamber B by means of the plug F,which is itted in a corresponding opening made in the cap E. (See Figs.2, 5.) This plug has a rightangled orifice, (see- Fig. 5,) so that bywithdrawing the plug the lubricant can be introduced through the orificein the plug into the chamber, and by inserting the plug in the cap theorifice is closed.

The truck and weight ofthe car are sustained on the outer end of thecar-axle. The inner part of the axle I provide with a movable collar, G,which can be adjusted along the axle .in the manner and for the purposeset forth.

2. The improved car-wheel, consisting offll4 car-wheel AI proper, havingthe lubricantchamber B, the sub-Wheel A2, having the 1u.,-brieant-ehamber B', the caps E E', sleeves e3, the packing e? e?,llfsaid parte being Qmhned v with relato t0 the. journal of a car-axle.,was

to form the annularpassage communicating from' the ChaniberB to B',forthepurpose set forth.

3. The car-Wheel A', its chamber B, wheels D, the sub-Wheel A2, itschamber B', Wheels D', the caps E E', stuing-boxes e, the annular`passage from chamber B toB', said parts being combined with the journalof a car-axle, and forming the improved car-Wheel A, to operate Ain themanner and for the purpose set forth.

In testimony of said invention I have hereunto set my hand.

CHARLES E. GANDEE.
